What is Stainless Steel
Plate 409 / AISI Plate 409?

HRS Ferritic is one of the finest and most trusted SS 409 importers, Stainless Steel 409 exporters and suppliers. SS 409 Plate is a chromium-based ferritic steel stabilized with titanium to improve weldability and resist intergranular corrosion. With approximately 11% chromium, it provides moderate corrosion resistance, excellent resistance to exhaust gas and thermal cycling, is magnetic, and offers a cost-effective alternative to austenitic steels in high-temperature applications.

  • Protective chromium oxide layer resists high-temperature oxidation
  • Ferritic microstructure provides thermal cycling stability
  • Titanium stabilization prevents carbide precipitation
  • Maintains mechanical strength at elevated temperatures
  • Resistance against stress corrosion cracking
  • Low nickel content for cost-effective heat resistance

Metallurgical Characteristics & Performance of SS 409 Plate

Each element in SS 409 plate plays a precise role in delivering exceptional durability and thermal performance.

Cr
Chromium
Provides corrosion and oxidation resistance by forming a protective passive oxide layer.
C
Carbon
Increases strength and hardness, but must be controlled to maintain weldability and corrosion resistance.
Ti
Titanium
Stabilizes carbon to prevent intergranular corrosion and improves weldability and high-temperature performance.
Mn
Manganese
Enhances strength, toughness, and hot working properties while acting as a deoxidizer.
Si
Silicon
Improves oxidation resistance and high-temperature performance and aids in deoxidation during steelmaking.
P
Phosphorus
Slightly increases strength but can reduce ductility and toughness if present in excess.
S
Sulfur
Improves machinability but may reduce ductility and weldability when excessive.
Fe
Iron
Forms the base structure of the alloy, providing overall strength and magnetic properties.
